Well, Wii has an extra mode or two, but 360 has presumably better online. If you don't care about graphics in a game like Guitar Hero, I'd suggest the Wii version but you certainly can't go wrong with the 360/PS3.
# of games above 75 on Metacritic (including downloadable):
360: 241 DS: 144
PS3: 152 PSP: 126
Wii: 85
